A Special Edition including the Mythical UAD Collections of Analog Processor Emulations
One of the core features of the Apollo is Real-Time UAD Processing. It allows you to use the entire catalog of UAD plug-ins with almost zero latency. The Apollo x4 Heritage Edition goes even further, as it comes with 10 premium plug-in collections valued at over € 2,400, including the full suite of UA Teletronix, 1176 and Fairchild compressors, preamps Unison Helios Type 69, V76 and UA 610 pickups, all Pultec EQs, Oxide Tape Recorder and Pure Plate Reverb. These high-end processors included in the Heritage Edition come on top of the “Realtime Analog Classics Plus” bundle that comes with the Apollo x4. No other professional audio interface comes with a collection of classic analog processor emulations as well. complete.

Four Unison Preamps - The Sound of Neve, Helios, API, Avalon, etc.
The Apollo x4 Heritage Edition is equipped with four Unison mic preamps, which allow you to record with the perfect emulations of the Neve, API, Manley, SSL, Avalon, Helios and Universal Audio mic preamps. Exclusive to Universal Audio, Unison technology offers proprietary hardware / software integration that accurately reproduces the sound of these legendary tube and solid-state mic preamps - including their input impedance, their stages' sweet spots. gain and the circuit behaviors of the original models. You can also find Unison technology on the two Hi-Z instrument inputs on the front of the Apollo x4; it adapts the impedance and gain when using guitar and bass amp models from Fender, Marshall, Ampeg, etc.

State of the art A / D and D / A converters
With thousands of hits and hundreds of Grammy Award-winning albums to their credit, Apollo interfaces are used to create great-sounding music every day. To further improve on the previous generation, UA engineers reworked the Apollo x4 audio converters to deliver an impressive 127dB dynamic range and -117dB harmonic + noise distortion. This gives you wide, natural sound that easily rivals much more expensive high-end converters.

LUNA Recording System - Full Integration with Apollos, to Work Fast and Intuitively
All Apollo X series interfaces work with major Digital Audio Workstations (DAWs) including Logic Pro, Ableton Live, and Pro Tools. But they become fully integrated recording systems with LUNA, a powerful Universal Audio application available on Mac. Thanks to its Accelerated Realtime Monitoring ™ technology, LUNA allows you to record and mix within a single highly intuitive interface with an unlimited number of tracks, full support for AU plug-ins and access to an exclusive suite of LUNA Instruments and Extensions.

Professional Performance and Flexibility
Apollo x4 Heritage Edition users can combine up to four Apollo Thunderbolts and six UAD-2 devices in total, an ideal solution for increasing I / O and DSP as their studio grows. And if they add an additional Apollo X rack to their studio setup, they'll be able to use the Apollo x4 as a desktop-sized monitor controller while still enjoying its additional I / O and DSP power. . With its four Unison compatible preamps, its six line outputs and its ADAT / S / PDIF optical input - as well as its remote monitoring controls and its integrated Talkback microphone - the 12 inputs and 18 outputs of the Apollo x4 Heritage Edition guarantee you recording and mixing quality worthy of professionals.
